To all whom t may concern:

Be it known that I, WILLIAM J. GOING, a citizen of the United States,residing at Amsterdam, in the county of Montgomery and State of NewYork, have invented certain new and useful Improvements in Yarn-Treating Machines, of which the following is a full, clear, and eXactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to yarn treating apparatus, and particularly toapparatus for '-.vashing, scouring and dyeing yarn.

One of the objects of the invention is to provide a practical andefficient machine of the character referred to. Another object cf theinvention is to provide a simple construction of machine wherewith longdelays, due to possible abnormal operation, as by misplacement of theyarn, are avoided. Another object of the invention is the provision of apractical machine wherewith breakage of the machine and of the yarn andsoiling of the latter are largely avoided.

' Other objects will be in part obvious and in part pointed outhereinafter.

' The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims.

-lfn the accompanying drawings forming part of this specification, andwherein similar reference characters refer to similar parts throughoutthe several views,.

Figure 1 is a front elevation of a machine of the character describedfor scouring yarn;

Fig. 2 is a rear elevation of the machine shown in Fig. 1 and showingalso a portion of another similar machine at the left-hand side;

Fig. 3 is a detail perspective view of the form of shift mechanismemployed in Figs. 1 and 2;

Fig. 4 is a front view of a portion of Fig. 1, illustrating a modifiedform Y of shift mechanism associated therewith;

' Fig. 5 is a rear view of the machine shown i Fig. 6 is an end view ofthe shift,v mechaclosed as embodied in a machine similar to that formingthe `subject-matter of applicants companion application filed March 11,1915, No. 13,596 (1915), tho-ughvit is to be noted thatthe inventionl iscapable of being differently embodied without departing from the spiritthereof. 1 is the frame of the scouring machine, the various shapes ofportions of which will be best understood from the drawings, and whichmay be `varied indefinitely in shape according to the detail of theremainder of the apparatus.' 2 an electric motor driving the apparatusthrough a gear 3. 'A second gear 4 is mounted on a countershaft v5, asis also a gear 6. The main shaft of the machine is numbered 7 and isYdriven by a gear 8, meshing with the gear 6 through the collar of laclutch 9. A worm 10 drives the worm wheel 11 on the shaft 12, presentlyto be referred to, and a gear.13, through another gear 14 on the shaft15 and worm 16 upon that shaft, drives a worm gear 17 turning the shaft18. On the right-hand end of the shaft 7 (Fig. l) is loosely journaled abevel gear 19 driving another bevel gear 20, presently to be furtherdescribed; a clutch 21, the collar 22 of which is fastened to the shaft,connects the gear 19 thereto or throws it out, as may be desired.

Turning now to Fig. 2 in connection ywith Fig. 1, it will be seen thatthe apparatus is located in a tank 23, and in part consists of aconveyer for the material to be treated, l

this .conveyer comprising two aprons, marked 24 and 25. rlheconstruction of these aprons may be similar to that set forth in theprior application above referred to,

rand reference thereto maybe had for a fuller description. It issuflicient to here state that the aprons 24 and 25 have a circuitouscourse in the liquor in the tank 23, and that the yarn is carried by andbetween these aprons into, through and out of the liquor. i;

The yarn passes into the machine from thel tablev `26 on one side {ofthe machine andl 30 of the upper part of the machine frame register'with the outside of the tank or vat 31 of a Isecond machine. From theshaft 18 of the lower roller 2S, by means of a sprocket, is driven atransfer roller 33 carrying the yarn to the apron 34 of a second machinesimilar to the first. The yarn be ing brought up from the rst tank onthe apron is transmitted to the squeezing rolls, and is then carried tothe transfer roll 33, which in turn drops it upon the apron 34 of thesucceeding machine.

` As these machines are driven by power and the load upon them variesconsiderably,

an ample surplus of power must be .provided; and as the squeezing rollsare under Vvery heavy pressure, any operation about the machines isdangerous unless abundant facilities for stopping them quickly beprovided. YThis has been arranged in the ap.- para'tus hereinillustra-ted. Referring to Figs. 1, 2 and 3, one form of stopping systemis illustrated. The lever, or member, 35. is an ordinary shifting leverworking through the link 36, the lever 37, pivoted at 38 and operatingthe collar of the clutch 9, connecting the gear 8 to the shaft 7. A

spring 39 of ample power to throw the lever is connected to the link 36and as a factor of safety another spring 40 is also provided, so thatwhen the lever 35 is released, it will certainly be operated. The lever35 l is held in place hy a rotary dog, as a cam 41 formed upon a gear42. A notch behind the cam holds the lever 35 in place, but when thegear 42 is revolved by moving the handle 43, the inclined surface of thecam is presented to the lever 35; the springs 39, 40 pull over the lever35 and shift the clutch 9, bringing the machine to an instantaneousstop, inasmuch as the worm gears 10, 16 serve as effective brakes. At 44is an abutment, or board, mounted rigidly upon a shaft 45; connected tothe shaft at each end is a bell crank lever 46. On one side of themachine is a bar 47, connected at one end to the lever 43 and sliding ina guide 48, a stop 49 limiting its movement. One. of the bell cranklevers 46 connects with this bar at a slotted end 50. If the hand or theyarn is thrust againstfthe board 44 with sufficient "force, the lever 46will, by the rotation of the shaft 45,- be thrown to lright Fig. 1,throwing w-itlritthe bar 47 and thus operating the lever 43, turning thecam 41 so as to release the lever 35, and throwing out the main clutch 9of the machine. On the other side of the machine the corresponding'bellcrank lever 46 is connected to a sliding bar 51, to which are alsoconnected the handles 52, 53, the latter working against a spring 54. Atthe lefthand end of the bar 51 (see Fig. 2) is a lever 55 and anabutment, or board, 56, is connectedto the shaft to which this lever iskeyed. This board, as will be observed, is in front of the rollers 23,29, which squeeze the yarn, and it will be obvious from the connectionsthat if this board be pressed toward the "rolls, it will throw the bar51 to the left and operate the bell crank lever 46 and bar 47, thus, asalready explained, throwing out the main clutch of the maf chine.

The construction hereinbefore described is similar to that of the priorapplication above mentioned, andis appended with the view of enablingone to herein clearly understand the general construction and operationof the machine, and particularly the construction and operation of thestopping mechanism and its relation to the other functions of the priormachine. 1t will be observed that, in order to stop the machine bytheconstruction hereinbefore described, the cam 41 has to be turned, andthat the turning of this cam is accomplished by a movement of the rod47, in consequence of which the boards 44 and 56 are likewise turned.

lWhen the machine is running, it may be desired to stop it withoutdisturbing the boards 44 and 56, and to this end the constructionillustrated in Figs. 4, 5 and 6 has been devised, in which,nevertheless, the features of stopping by proper movement of the boardsor abutments 44 and 56 are maintained. Referring now more particularlyto Figs. 4, 5 and 6, the numeral 56 indicates the board or abutment infront of the squeezing rolls and 55 indicates the bell crank lever ordependingarm which is moved by said abutment, as hereinbefore described.Applicant has chosen to explain the different form of shift or stopmechanism in connection with the board or abutment for the squeezing'rolls, but it will be obvious that its construction and operation are aswell applicable to the board adjacent the feed table 26, and in diversother places. rlhe abutment lies in front of the squeeze rolls 28 and 29with its lower edge spaced from the adjacent apron a sufiicient distanceto permit the passa-ge of yarn of normal depth to said rolls. Theabutment 56 extends the full width of the aprons and should the yarn beAhunched ormassed so as to increase in thickness at any point in itswidth it will be forced against. the abutment by the movement of theconveyor aprons and will turn the abutment on its axis. The 'lower endof arm 55 is in coperative relation with a rod 57, disposedlongitudinally of the tank e 23 and guided in keepers 58 on one side ofthe tank. Vhen an abnormal operation of the machine occurs, as by reasonof the bunching of the yarn hereinbefore referred to, the presentinvention provides for automatically cutting out the driving relationbetween the driving and driven elements, and this cutting out isreferred to herein by the term disengaging or the like, as being asimple term to indicate the function accomplished. This term is, ofcourse, intended to include any of the many ways in which a machine isdirectly connected and disconnected from its power, as by clutches,belt-pulleys, etc. l p

The numeral 59 indicates a manually operative member, or shift lever,connected by a link 60 with the lever 37 fulcrumed on the side of thetank and connected to the rotatable driving clutch or element 9 whichrotates with the shaft 7. By shifting the lever 59 the driving clutch 9may be engaged and disengaged with the driven gear 8 and thus powerapplied and eut off from the conveyer aprons. The lever l59 is fulcrumedon the side of the vat in any suitable way, as by being pivoted in thestrengthening brackets 61 fastened to t-he vat. The numeral 62 indicatesa movable device 'or member, which, in its specic aspect, is aVmotor-device and comprises an upstanding arm pivoted on the same axis`as is the lever 59 and having a handle 62 and a lower horizontallydisposed arm 63 on which is aY weight 64 adjustable on arm 63, theweight tending to move the device 62 in the direction indicated bythearrow A. The device 62 is herein termed a motor-device, inasmuch asit automatically moves in a predetermined manner under the influence ofthe weight 64 when it is free to move, and energizes other parts. Themotor-device is adapted, when moved in a predetermined direction, tomove the lever 59 in a direction to cause disengagement of the drivingand driven clements hereinbefore referred to, so as to cut on theapparatus from its power, and in the present embodiment is provided witha projcctiorn'a square lug 65, which engages the edge of the lever 59and shifts said lever. When the shift lever 59 is in such position thatthe drivin g and driven elements areengaged, the motordeviceV 62 is heldin such position as not to energize the shift lever 59 by means of astop-dog 66 which is adapted to be moved into and out of engagement withthe motor-device. ln the present embodiment the dog 66 is rotatable intoand out of position in the path of the motordevice and is comprised in asemi-circular gear 67, the flat face 68 of which may be disposed acrossthe path of the motor-device or outside of said path. `AThis dog isrotatably of the shaft being provided with a triparm 71 fastened theretoso as to rotate therewith and with the rotatable dog 66. The

i elements just referred to are so relatively arranged that when themotor-device 62 is drawn back into the position from which it moves tocause disengagement of the driving and driven elements, the dog -66 maystand opposite the edge of the element 62 so as to stop disengagingmovement of said element, and at this time the trip-arm 71 will be in ahorizontal position. This latter arm is held in such horizontal positionby means of a trip 72 carried yby an arm or lever 73, one end of whichis pivoted to a iiXed bracket 74, and the other end of which is slottedfor engagement of a pin 7 5 carried by therod 57. The rod 57 is strainedin a direction to place the trip 72 beneath the trip-arm 71 by means ofa spring 76. The trip 72 is pivotally connectedl to the lever 73 so thatit may beV rotated upwardly to escape the end of the trip-arm 71 atcertain times, its lowermost position being determined by a stop 77 onlever 73. On the shaft is a rotatable sleeve 78, having at one end atrip-arm setter, comprising an arm 79 rotatable with said sleeve anddisposed opposite the trip-arm 71, the sleeve 78 being provided with ahandle 80 for conveniently rotating the same. The depending arm 55 maypass through a slot in the rod'57 or may abut against a pin .81 on saidrod, as illustrated. y

The operation of the machine in conjunction with the form of shift orstop illustrated in Figs. d, 5, and 6 will be apparent from theforegoing description, but may be briefly described as follows: When theyarn becomes so hunched as to move the abutment 56, the arm 55 will movethe rod 57 against the resistance of the spring 76 and will cause thelever 73 to rotate, thus drawing the trip 72 from beneath the triparm 71so that the latter will be free to rotate. The weight 6d will then causethe motor-device or arm 62 to advance in the di- -rection to cause thelug 65 to engage the drawn back. The sleeve shaft 7 8 is then'rotated-bymeans ofthe handle y8,0 in the direcaen wthatthe trip. setting. arm79,Will

rise and lri'ft the trip-arm 71 and sweep the same pasty the endot thetrip 72, the latter rotate, causing the gears on the dog and shaft toset thev dog into stop position relative to the device 62. The trip-arm72 will descend to its position limi-ted by the stop 77, and thetrip-arm 71 will rest thereon and hold the dog 66 against the pressureof the device 62. lt will be observed that the tripP lever 59 may beoperated freely sol as to cut in and cut out the power irrespective ofthe movements of' the device 62. Preferably when the device is set inposition with the driving and driven elements engaged, the Vtrip leveris lockedL in its position by means of a paw-l, or coupling, 81 pivotedthereto and engaging the lug` G5, this pawl having a handle 82 alongsidethe handle of lever 5-9. The lever 59, at its upper part, is guided in aslotted bracket 83 secured to the tank wall.,

Fig. 7 illustrates the invention embodied in a form of dyeing machinehaving a conveyer comprising a rotatable reel carrying rotatable yarnsticks, each stick having a star wheel adapted to cooperate with adevice to eiiect turning ofl the sticks in one direction on their axesduring operation of the dyeing machine. Turning of the sticks in theopposite direction is restrained by the customary ratchets. rEhe reel isindicated at 100, and the sticks 101 are provided with star wheels 102and pawls 102. They are shown inside the tank or casing 103, the starwheels coperating at the top of the tank with a lstick-turningdevicecomprising a pivoted arm or abutment 104: on the inside of the tankhaving an arm 104 iiXed to the pivot 105 at the outside of the tank.rllhe reel normally rotates in the direction of the arrow B. Should anyyarn stick be prevented from rotating on its mounting in the reel, thearm 104C will be pressed and rotated on its axis in the directionindicated by arrow C. 106 is a weighted lever pivoted at 107, one of itsarms 108 being in the path of a pawl 109 pivoted on arm 104, this pawlbeing held to rotate with arm 101 in the direction of arrow C. The otheror depending arm of lever 106 is linked to a lever 110 pivoted on theframe at 111, one end of this lever cooperating with the pin 81 to movethe rod 57 against the resistance of the spring 76 to remove the trip 72from beneath the trip-arm 71 and permit the dog 66 to rotate out of theway of the motor-device 62. The stop or shifting device illustrated inFig. 7 is the same as that shown in Figs. 4, 5 and 6, except that allits parts are on the same side of the tank. v

y For discharging the contents ofthe tanks when desired,a valve, asillustrated in` Fig. 1, may be employed. The numeral l2()v in- ,snasasea dicates a valve casing communicating with the tank,y the valvebeing indicated at 121 and its seat at 122 opposite the outlet. A footlever 123 is fulcrumed on the valve casing, onev arm of this leverhaving a pedal piece 124 and the other arm having a pin and slotconnection with the stem 125 of the valve. Pivotal-ly connected to thefoot lever- 123 is a pawl 126, the notch 127 of which is adapted toengage a stationary member 128 to hold the valve in open position, aspring 129 being connected to the pawl and the member 128, so that itsstress tends to urge the pawl notch against the member 128,v and alsotends tol close the valve and hold it closed when the pawl is releasedfor interlocking engagement with the member 128. The pawl 126 has apedal piece 130, depression of which lifts the notch of the pawl out oflocking engagement with member 128, permitting the spring 129 to, closethe valve.

As many changes could be made in the above construction and manyapparently widely different embodiments of this'invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanyingldrawings shall be interpreted as illustrative and not in a limitingsense.
